Lion brings a number of new features to Apple's flagship
operating system, including a number of iOS staples like multi-touch
gestures, auto saving for apps, full screen aps, and a fully integrated App
Store. Other additions include iCal 4.0 and an overhauled Mail app that takes a
few design cues from the iPad's version.

Apple will also unveil iOS 5 at WWDC for the iPhone, iPod touch, and iPad. Apple's iOS UI has
stayed pretty much the same since it was first introduced in 2007. Sure, there
have been major features like multitasking and folders that have been tacked
onto the OS, but it's still a design that dates back four years.

Apple is sure to boast of "over 100 new features
added" when iOS is introduced next month, but the one feature request
that is at the top of nearly everyone's wish list is an overhauled notification
system. The current notification system in iOS is beyond antiquated and has
long been surpassed by superior implementation from HP/Palm and Google. Apple has
no excuse not to fix this obvious shortcoming with iOS 5, so expect “magical” notifications
“done right” to be displayed front and center during the keynote.

Finally, Apple made a slight mention of its upcoming iCloud
online music service in its press release, referring to it is as an "upcoming
cloud services offering." Apple already reportedly
has deals in place with three of the four major record labels with regards
to licensing. The only holdout so far is Universal Music.
